Reading Rape And Answering With Empathy: A New Approach To Sexual Assault Education For College Students, Brianna Jerman

USF Tampa Graduate Theses and Dissertations

The issue of sexual assault on college campuses is addressed in part by a mandate that all college students complete some form of sexual assault education. While current education programs have proven successful in teaching bystander education and dispelling rape myths, they have not proven to increase reporting rates while also decreasing the number of sexual assaults. This dissertation makes a pedagogical argument for a new approach to sexual assault and prevention education at the college level that would use literary rape narratives to dispel sexual assault myths, teach trauma theory principles, and address intersectional aspects of rape culture with …

Assessing The Effects Of Observational Conditioning And Response-Contingent Pairing On Increasing Vocalizations In Children With Asd, Sydni Chance

USF Tampa Graduate Theses and Dissertations

Children with an Autism Spectrum Disorder (ASD) often display impairments in communication. More specifically, children with ASD may have difficulty developing language skills, for e.g., delay in verbal behavior, limited echoic skills, and/or lack of functional communication. A common way to combat this deficit is by increasing vocalizations in these children. Previous research has used various procedures to attempt to condition vocalizations as reinforcers, such as stimulus-stimulus pairing, response-contingent pairing (RCP), and operant discrimination training. Another procedure for conditioning stimuli is observational conditioning (OC), which is a type of observational learning. However, OC has not been assessed as a procedure …

Measuring And Utilizing High-Dimensional Information Of Optical Fields, Ziyi Zhu

USF Tampa Graduate Theses and Dissertations

Currently, many areas of optical techniques including imaging, inspection and communication emphasize the utilization of the high-dimensional information encoded in optical fields. There is also a requirement for novel measurement techniques to extract this high-dimensional information with high-speed and accuracy. We firstly introduce a scan-free direct measurement technique that is capable of simultaneously characterizing the amplitude and phase of a coherent scalar optical field. Our direct measurement approach is constituted of a weak polarization perturbation which is followed by the recording of a polarization-resolving imaging process. The weak perturbation rotates the linear polarization on the spatial frequency domain of the …

Chemolithotrophic Denitrification Of Nitrate Contaminated Groundwater Using Sulfur-Bearing Minerals, John Sutton

USF Tampa Graduate Theses and Dissertations

Nitrate contamination in groundwater resources poses a serious threat, not only to the health of those who would drink it, but also as a potential nutrient for eutrophication. Current methods of nitrate removal can efficiently remove nitrate below 10 mg/L as nitrogen, but may require resources unavailable to small community water systems (SCWS). Sulfur-oxidizing biological denitrification is a promising alternative that may be more suitable for SCWS. Sulfur-oxidizing denitrification has previously been shown to have a high nitrate removal efficiency; however, it produces water high in sulfate. Utilization of sulfide-bearing minerals, rather than elemental sulfur as an electron donor, may …

Autonomy, Suffering, And The Practice Of Medicine: A Relational Approach, Michael A. Stanfield

USF Tampa Graduate Theses and Dissertations

In this project, I argue that the conventional view of personal autonomy that is operational in contemporary American culture, bioethics and medical practice places undue emphasis on individualism and a limited range of personal qualities and attributes (such as self-sufficiency). Instead, I argue in favor of a relational approach to autonomy which recognizes that each person that exists has certain minimal connections or relations to others, and these connections/relations are identity-forming. Unfortunately, current medical practices have tended to overemphasize individuality and choice (consistent with the conventional view) while minimizing or excluding these relational aspects. As a result, informed consent and …
